Eco-Friendly Solvents in Oil Industry: Potential and Challenges for Future Use

What is it about?

The research presents an updated review of deep eutectic solvents (DESs) applications in oil industry operations, with a focus on asphaltenes. The research analyzed 157 publications, narrowing them down to 18 significant studies after excluding duplicates and irrelevant content. The scope involved investigating the mechanisms by which DESs interact with asphaltenes, such as solubility, charge transfer, hydrogen bonding, and π-π interactions. Of the selected publications, 14 were empirical studies primarily concentrating on the solubilization of asphaltenes using DESs. The research highlighted that DESs are environmentally friendly and economical alternatives to traditional chemical compounds used in oil operations. The findings underscore the potential of DESs for upstream and downstream oil operations, although the research emphasizes the need for further studies to support large-scale industrial applications.

Why is it important?

The study is important as it explores the potential of Deep Eutectic Solvents (DESs) as innovative solutions in the oil industry, specifically for handling challenges associated with heavy and unconventional oils. Given the increasing global demand for oil and the complexities in refining high-asphaltene content oils, DESs represent an environmentally friendly and economically viable alternative to traditional chemical compounds. By offering biodegradable, recyclable, and tunable properties, DESs hold promise for more sustainable and efficient oil extraction and processing methods. The study's findings could significantly impact upstream and downstream operations, paving the way for more sustainable practices in the oil industry. Key Takeaways: 1. DESs as Green Alternatives: The research identifies DESs as potentially greener substitutes for commercial chemical compounds in oil operations, capable of reducing environmental impact while providing similar or enhanced functionalities. 2. Mechanisms of Interaction: The study highlights key mechanisms, such as hydrogen bonding and π-π interactions, that facilitate the interaction between DESs and asphaltene molecules, crucial for inhibiting asphaltene precipitation and improving oil processing. 3. Growing Research Interest: An increasing number of studies, particularly in the last two years, emphasize the growing interest in DES applications within the oil industry, signaling a promising shift towards more innovative and sustainable approaches in oil extraction and processing.
